The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28
You'd like to think 1 is true. I wonder if it really is though. There are so many horror stories out there about people in University courses that will be paid off by a McDonald's employee. (Sorry if that's you).
Again you hope this is true, but much depends on where you are. You can have a mansion in a ghetto area and it is worth next to nothing.
I should hope so.
The 4th one is a physical relationship. If the person is driving all the time it is true. There is a positive relationship.
The last one would have a random result.
All of these or none of them could have positive results. If you treat it as a pure math question, 1 should, 2 should, 3 should, 4 should and 5 should not. This question is far too subjective to get 100%. If you say anything at all, arguing it is very worthwhile. State your case and then shut up if your marker disagrees.
Hello Bubbleshi !
The first step you need to do is get everything in like terms.
- 1/6 and - 7 /4
Look at the denominator (number on the bottom)
6 and 4 go into 12, so lets check that out.
-1/6 , how can we get 12 from the denominator? Multiply it by 2.
So you multiply both the numerator (number on the top) and the denominator.
-1/6 becomes -2/12.
With -7/4, you want to get the 4 as a 12 (like terms!) so once again you multiply it by 3, and multiply the numerator as well.
-7/4 becomes -21/12.
-2/12 + (-21/12) is your final form of the problem.
You add -2 and -21 in the numerator, which is -23.
So its -23/12 which is your final answer.
Let me know if you need any more help!
